.W'ASHING MACHINE.

. Application filedNovemb'er 3, 1924. Serial No. 747,497.-

Our invention is an improve for washing machines, and partic larly for that type of washing machine'in whichthe impeller is positioned adjacent the top thereof-that is, the drive shaft extending thrlough the top, and thus actuatingthe impel er. a

The object of our invention is to provide an impeller which will create a rapidcirculation of water in the tub, thus causing the clothes to circulate and consequently will efliciently wash them.

impeller Another object of this invention is to provide an impeller in which the inner ends of the blade intersect to form a backing, thus forcing all the water outwardly and horizontally from the ends of said blade,

and upwardly toward the center of the impeller. Our impeller is designed to operate with the closed horizontal plate at substantially the surface of the water, with the thus none of the water circulated by the propeller will pass through this horizontal late.

p Another object is to provide a taperedtub which assists the downward circulation of the water.

In the annexed drawing in which our in vention is illustrated:

Figure 1 is a plan view of our impeller.

Figure 2 is a side view of the same. Figure 3 is an enlarged fragmentary sec tional view of our impeller.

Figure 4 is a'perspeotive view of a washing machine with our impeller positioned therein, and with parts broken away to show the construction thereof.

Figure 5 is an enlarged fragmentary sectional view of the washing machine tub.

\ Figure 6 is a. side View of a modified form of impeller.

Referring, more particularly to. the drawing, the washing machine 1 ,is provided with the usual cover 2, upon which suitable gearing 3 is-positioned to drive the shaft 4 upon which our impeller 5-is mounted. The tub A is tapered inwardly towards the top thereof, and the sides are corrugated as shown atB in Figure 5, the object of which described. The impeller .5

extending downwardly to the water,

from. Also the block from the end of the blades,

ber set 90 apart. The top 5 is not formed in a perfect circle, but the portions between the blades are cut away, as shown at 8, to

further lighten the impeller, and thereby reduce the load upon the driving mechanism.

A socket 9, is formed-in the center of the plate 6 in which the squared end of the shaft 4 extends, said shaft being secured to the impeller 5 by the coiipling. 10, which is suitably bolted to the top plate 6, A block 10: is pinned to the end of the shaft 4 by a pinlO", which extends from the sides of said block, and is adapted to engage a shoulder l0 in the coupling 10 to prevent the withdrawal of said block and shaft. The block 10Pis squared and this serves to rotate the impeller'5. A socket'9 is adapted to.

receive the block 10 when the impeller 5 is moved upwardly, that is, a knot or bundle of clothes may be formed under the impel ler, and in order not totear or mutilate said clothes the impeller may move upwardly away from them thus clearing itself there l0 is not rigidly mounted in the coupling 10, but may move slightly therein, 5 to tilt slightly of clothes appears on the outer edge thereof.

The inner endsiof the cut away, as shown at 11,- said out being a, gradual curvature so that the clothes will thus allowing the impeller whenever a bundle or knot blades 7 are slightly be momentarily caught upon the impeller,

and thus impede this movement outwardly.

In operation, the water is thrown outwardly from the outer edge of the blades 7, the solid center part preventingthe passage of the water therethrough, the rapid osciln lation of the impeller causing a rapid move ment of the water outwardly therefrom, downwardly along the flared sides ofthe tub, and thence upwardly towards said impeller, thus the clothes are drawn upwardly towards the centerof the impeller, and are thrown outwardly following the movement of the water from the end vof the blades '7. The fact -that the blades 7 extend to the center of the impeller 5prevents the; water from passing around the inner edge of said blades, and when the impeller is oscillated the water is compelled to move outwardly thus causing a rapid circulation of the water outwardly from said thereto impeller as Also this ohtward movement of the water well as upwardly carries the clothes along with it, and throws them against the corrugated surface of the tub A forming an abrasive action and thus more effectively cleaning the clothes. The frustro conical shape of the tub also assists in this circulationof the water downwardly from the impeller, and upwardly towards the same at the centerof the tub. This con-,

the top of a frustro-conical tub of a washing machine, comprising a flat imperforate top plate with a down-turned peripheral edge,

radially arranged blade members de ending from said top late inside of sai downturned edge; said blades intersecting at the impeller axial center and having them lower downedges recessed to form depressed portions at and about the axial center, a socket extending axially on said top plate, and a block in said socket adapted to reciprocably engage and support said socket; said block being .adapted to be secured to impeller rotating means of the washing machine.

An impeller for rotatable mounting in the ,top of a frustro-conical tub of a washing machine, comprising a'fiat imperforate top plate with a down-turned peripheral edge, radially arranged blade members depending from said top plate inside of said downturned edge; said blades intersecting at the impeller axial center and having their lower edges recessed to form depressed portions at and about the axial center, a socket extend:

ing axially thru the top plate into the intersection of said blades, a block in said socket; and means secured to the upper face of the top plate for reciprocably securing said block in said socket; said block being adapt- FRANK B. SOI-IUYLER. JOSEPH F. RUSSELL.
